Fig. 2

1 mm continuum as observed with the PdBI Widex instrument. The telescope was positioned in D configuration. Contours give the −3σ, −2σ, 0, 2σ, 3σ and then multiples of 5σ flux levels (1σ = 1.8 mJy/beam). The galaxy center is indicated by a black cross. The beam size is 2.4′′ × 1.3′′ and is indicated in the bottom-left corner. Pixel scale is 0.30′′. A color version of this figure is available in the electronic version.
